My opinion is that the battery is likely just getting weak with age - but it's likely not at the point where it needs to be replaced. I would cancel the appointment because they will likely just charge you an arm and a leg and not do anything. Keep it on the tender, and if it's cold out and you do a cold start, turn things on in stages with a few seconds in between to give the electrical system a chance to keep up.
